A little-noticed liberal group made a big impact in Tuesday’s Democratic legislative primaries in Milwaukee, ousting two longtime incumbents with attacks on their left and likely ensuring that no strongly anti-abortion Democrats will remain in the Legislature when it returns next year.

Wisconsin Progress easily won its targeted races with candidates it had helped recruit and train, with law student Daniel Riemer crushing Rep. Peggy Krusick, a three-decade veteran Democrat from Milwaukee, and community organizer Mandela Barnes stunning Rep. Jason Fields, who had served for eight years.

Another candidate backed by the group, Milwaukee County Supervisor Nikiya Harris, also won her Democratic primary for the state Senate. In Democratic Milwaukee these three primary victories essentially mean all three candidates will also win the general election.

The victories put in place Democrats who will stand with others in their party in opposing voucher schools in favor of public schools and supporting abortion rights, said Scott Spector, a former labor official who is now the executive director of Wisconsin Progress.
